Hi to all moogers! My first post here, so, pls. be kind. 
I decided to buy Voyager+RME for duophonic playing.
Also, 351/352 + 251 controllers and array of Moogerfoogers for semimodular synth built.
I had dilemma either to go this route or some real modular synths in racks, but finally decided for Moog.
My question is:
Will various modulations and manipulations done via 351/251 etc. on keyboard impact (via MIDI) the sound of RME?
I have no idea about that!
Thanks in advance to all.
Welcome to the forum!
Like what kinds of modulations?
I think that the keyboard is sending Note on and off messages, velocity and aftertouch messages to your RME only. So no externally applied CV voltages to or from anywhere (unless they are going IN the RME themselves) will affect the sound of the RME.
Just like someone posted on here today that the Voltages available OUT of the Voyager are there and are independant of the actual panel settings on the Voyager, with the exception of the LFO.
I hope that im accurate about this!

i think of midi as virtual knob twisting and button pushing, that does what it wants to, such as changing patches, or parameters on one synth when i change them on another, this really annoys me, but i have learned to tame the beast with midi filters, which sadly are not included in every synth, and CV as that thing with physics that does what it should, with a plethora of cables that modulate only what i want them to. i find that both have places, but CV is a little less evil
Thanks Eric. 
I thought it is like that, but anyway I hoped.
Do you think that changing patch number (particular saved sound that is equal on both synths) on keyboard will change same on RME (should IMO).
Next point is that playing with CV and manipulating various aspects of Voyager keyboard voice (that is voice 1) would apparently not produce same changes on RME. Is there any solution that will duplicate CV manipulations done on keyboard’s voice to RME’s voice (something like CV duplicator-router)?
In such scenario duophonic mode would be real two equal voice synth what is one of purpose for my choice.
I should point out that I have plenty of other classic and modern analogue synths (and no Minimoog 
) and such versatile functionality is something I would like to explore now.
CV multiples could be used to send the CV to both synths, and are included on the 251, and i believe the 351 as well, and if the voyager is like my phatty then there are menu options to turn on and off program change messages, both send and receive. Also i recommend you read the manuals, they are well written and full of inspiration.
Does it mean that particular CV parameter change can simultaneously be patched to both keyboard and rack? Are there sufficient outputs on 251/351?
I think that if you do anything on the controls of the Master, it will happen on the slave. Changing presets, tweaking presets or designing sounds from scratch will do this.
I am pretty sure that if you sent a CV to the Masters pitch, it will not affect the second pitch. So any source that you want to route you will have to route to both destinations. So what you might want to consider is investing in some multiple modules from synthesizers.com (I don’t believe they require power and a simple rack frame will hold them.) if you plan on doing a lot of modular patching. This will be necessary if you intend on using your RME specifically for a second voice of the Voyager, because as you are already probably well aware, the RME could be controlled independantly and be just as good.
The vx351/cp251 only gives you three mults and 1 mixer. Mults are your friend. I don’t know if the 352 has mults.
Just think, whatever you want to patch, you have to patch twice.
Thanks guys, you’re great indeed!
In all scenarios it’s clear that I need two 351 and question is would I also need two 251 (although they are not co-ordinated by each other).
I’ll see about multiple modules, thx. for referencing.
BTW guys, is there any point of adding some Eurorack or similar formats modules to whole game? They look appealing, but I wouldn’t like to be completelly lost on that.
Heres a dotcom multiple for 58 bucks. No power supply is needed. Get yourself a couple of these and you should be set.
Put them in one of these rack frames for 65 bucks
You might want to get a few more while you are at it. After all you did want to go modular right?
Ive researched the Eurorack a tiny bit. I was looking at the harvestman polivocks filter for 295 from analoguehaven.com. its a great sounding filter.
The only problem with euroracks are that they need a different rack frame to support them, they use different voltages than the MOTM sized or MOOG sized modules, and they use 1/8th sized patch cables. I don’t want to turn you away from this format because its very popular and it is a good time to be looking at Eurorack stuff. Its a different ballgame though but for myself, who also wants to get into modular, I want to be as Moog compatible as possible before I branch out and get a second modular synth in a Eurorack.
Dotcom plays extremely well with Moog, they are practically Moog clones.
Now 2 cp251’s would be very nice, but its not a necessity. Rather than get a second cp251, you might want to consider an MP201, since right now the price is lower and they just made a brand new OS for them. It offers 4 LFO’s, repeating envelopes and a lot more. I am working on completing a set of Foogers, (I have 3 to go) and I want a second 251, because having 2 S&H that are seperate, 2 lag processors more mults and attens is nice, and using one mixer to mix voltages and another for audio is another very nice thing. Having 1 CP is a necessity, but two or more is a luxury!
Don’t let anyone tell you that more than 1 of a particular Moogerfooger is redundant because the more you get to patching stuff, the more you will want. Whether or not you want a second one or want to go eurorack is your option, but I have heard that it is easy to get pulled in by euroracks.
In the end its all about a grande system, which you are working for and you definately have good taste if you ended up here!

Thanks for generous post Eric.
I get it now and it seems that whole new world is opening.
I already have several Moogerfoogers (as guitar effects mostly), but decided to add all rest, incl new pedal, so it will be high start with full Moog synth’s lineage, except Little Phatty 
Also, I pre-ordered Taurus 3 some months ago, as I was always fan of that fat bottom sound.
In relation to patch cables, is there any particular requirement to their quality (they don’t pass audio, so probably not). I’ve found some rather inexpensive, so most likelly there is no need to buy from Moog
As far as sending control voltages goes, you only need Tip Ring Sleeve Cables, but they don’t have to be exceptional quality. You are only sending CV through them, not audio. If you really want good audio cables, the monster cables are expensive and supposedly have lifetime warranties.
If you use tip sleeve cables trying to send multiple cv signals to the same pedal then the signal will short to ground unless you are using tip ring sleeve cables.
Strangely, Moog isn’t selling TRS cables, at least not the last time I checked.
Eric
Look here I’m confused a bit.
Moog sells TS cables, it was even somewhere written that for patching mono cables should be used.
I bought several bundles of TS cables (rather cheap though) 
, so does it mean they will be useless or functionally limited
OK, it’s clear that for pedals inputs only TRS cables provide full functionality.
So, wouldn’t be better to use TRS cables everywhere, as seems they can function without limits?
Is any typical TRS cable available good for that (in manual there are some explanations that are not completelly clear to me)
Honestly, these questions are starting to get out of my knowledge. In the interest of full disclosure, i have very few TRS cables, most of mine are MONO just because they were cheap, and I don’t usually do things like route 2 CV sources to 1 Fooger…at least not yet.
I hope someone will chime in. But until then, read the Ring Mod manual.
Eric
Thx Eric.
I went through several manuals and everywhere is written same, I would say 80% clear and choice of TRS cables is related only to Foogers. When I get all system I’ll need to experiment a bit.
What I don’t fully understand is would it be preferrable to use TRS just anywhere and forget about TS-TRS confusion that actually exists in manuals. In terms of buying cables, there is virtually no difference (for example 10 3ft. cables TS or TRS sold by same seller for appr. 25 $)
Only question is about danger (if there is any) of connceting outputs/inputs with wrong cable (seems like it is rather small chance to destroy something, but still).
there is no danger in using a ts cable instead of trs, the only difference in their function with the foogers is that if you use a ts cable on one of the cv inputs you will not be able to use an expression pedal on any of the others, at the same time, thus they are only important if you are using an expression pedal.
Is opposite same: TRS vs. TS (in terms of safety)?
Thanks Jeepo for clarifying.
You should be using TRS cables for CV patching; Using TS will give you only the positive side of the signal, so for instance with a TRI wave LFO going into the LPF Cutoff, you’re only going to get the upsweep of the LFO, instead of the up-down associated with going from +2.5 to -2.5v. You will also lose the ability to use expression pedals if you have TS cables plugged in as this shorts out the voltage to the ring contact.
BTW I’m right there with you about the weirdness of Moog selling TS cables for products that are TRS recommended.
Without being fully aware of that I ordered bunch of TS cables just to learn later that there are NO SINGLE benefit of using TS over TRS followed by loss of some functionality on several patching scenarios.
Wouldn’t be simplier to put everywhere in the beginning of manual or their Internet site ‘USE TRS CABLES’
